The new Pew Research Center study shows religious affiliation has fallen to a new low across America, according to researcher Greg Smith.

“We asked them, when it comes to your present religion, ‘what, if anything, are you? Protestant, Catholic, Jewish, Muslim?,'” Smith said. “And this large group of people, about one in five American adults, are now telling us that they don’t associate with any particular religion.”

In the Midwest, the number of the religiously unaffiliated has grown from 15 percent in 2007 to 19 percent today.

The biggest growth in religious disaffiliation can be found in the Northeast, although the biggest percentage of those who describe themselves as religiously unaffiliated live out West.
